6) Parallel bar dips.

This exercise also works the middle and lower pectorals.
The subject holds him/herself at arms length on two parallel bars the slowly lowers him/herself. At the bottom of the motion stops for a second then pushes up.
The exercise provides for great range of motion, however one needs to pay extra attention to how he/she executes it. The reason is that if one does the dips leant back a bit it turns into a triceps exercise. Leaning forward works the pecs.
Extra considerations: crossing the feet and bending your knees will shift your center of gravity thus leaning the upper body forward.
